[Blood flow measurements of the utero-placento-fetal unit]

Examination techniques suitable for evaluating uteroplacental blood flow are of vital clinical interest. Whereas flow measurement using radioisotopes only catches the maternal side of the placenta, pulsed ultrasound Doppler technique makes it possible to examine the maternal and fetal side of the uteroplacental unit. The results of the examination show a good correlation to the newborns' birth weight.
